A Guide to Best Practice in the Specification and Use of Fire-Resistant Glazed Systems

This best practice guide has been developed by the Fire Resistant Glazing Group (FRGG) of the GGF to help all those who specify, design, supply, install, and depend on fire-resistant glazed systems. We also have in mind regulators and inspection authorities whose task it is to enforce regulations as they apply to protection against fire, as well as insurers whose prime concern is property protection and risk management.
The fire environment is hostile and its effects can be catastrophic for both life and property. The occurrence and growth of fire is also essentially unpredictable and uncertain. It is therefore critical that the products we provide for fire-resistance measure up to the highest possible standards concerning both the level of performance and the consistency and reliability of performance. In that respect we have a shared duty of care with all those involved in the chain from specification through to installation.
The FRGG represents a broad cross-section of the fire-resistant glazing industry. Members include representatives of manufacturers and distributors of glass, glazing seals and frames, product testing authorities, certification bodies, and glaziers. We have pooled our collective expertise and knowledge to provide a unique, definitive guide on behalf of the industry. All members of the FRGG committee have participated in its development and endorse its content.
A primary objective for the FRGG is to lead by example in setting appropriate standards for the fire-resistant glazing industry and to encourage the widespread adoption of these standards. We hope that our best practice guide is a step along this road. In this respect we hope to work with organisations such as National Building Specification Ltd in assisting designers and specifiers to develop appropriate specifications for their buildings. We therefore intend that this guide will provide additional advice and guidance in support of the NBS L40 document concerning the specification of glazing where specialist fire-resistant glazed systems are required.

PAS 2016:2010 – Next generation access for new build homes guide

This Publicly Available Specification (PAS) provides guidance and a practical framework to identify the recommendations for digital communications infrastructures to and within new build domestic dwellings, supporting effective installation in new build homes.
The PAS addresses: 1) single dwelling units, i.e. houses which are individual dwellings not sharing common parts (other than party walls) with other houses; and 2) multi-dwelling units, i.e. housing where multiple separate housing units for residential
(i.e. non-commercial) inhabitants are contained
within one building.

The PAS is not intended for:
a) other multiple occupancy buildings such as hostels, i.e. where residents having their own rooms share facilities;
NOTE For example common kitchens.
b) community-wide wireless infrastructures; and
NOTE While these are important in the provision of digital infrastructure, they are not within the scope of this PAS.
c) the external provision of digital infrastructure to locations where wired infrastructure is not practical.
NOTE This is for further study.
The PAS is intended for house developers and builders, and all those concerned with supplying, installing, commissioning or operating digital infrastructure and related services in new build homes.
NOTE The intention is not to mandate a specific technology or supplier, but to identify a minimum standard of connectivity which can be fulfilled in a number of ways.

Radon: guidance on protective measures for new dwellings

This report gives guidance for reducing the concentration of radon in new dwellings, hence reducing the risk to occupants of exposure to radon. It provides practical details on methods of protecting new dwellings. This 1999 edition of the report replaces guidance published in 1991 for Cornwall and Devon and revised in 1992 to include parts of Somerset, Derbyshire and Northamptonshire.
The principal changes over previous editions reflect greater knowledge of radon-prone areas and the advances made in developing practical costeffective protective measures. In addition, the development of the protective measures and the monitoring of their effectiveness has indicated that the general approach to radon protection should be reconsidered and should embody the findings of this research.
Radon is a colourless, odourless gas which is radioactive. It is formed where uranium and radium are present and can move through cracks and fissures in the subsoil, and so into the atmosphere or into spaces under and in dwellings (Figure 1). Where it occurs in high concentrations it can pose a risk to health. Whilst it is recognised that the air inside every house contains radon, some built in certain defined areas of the country might have unacceptably high concentrations unless precautions are taken. In the UK, the granite areas of South-West England are of principal concern, but high concentrations of radon are also found in some other parts of the country.
Requirement C2 of Schedule 1 of the Building Regulations 1991[1] for England and Wales states that: ‘Precautions shall be taken to avoid danger to health and safety caused by substances found on or in the ground to be covered by the building’. The Approved Document[2] states that: ‘The precise areas where measures should be taken to provide protection against radon are reviewed by the Department of the Environment, Transport and the Regions (DETR) in the light of advice from the National Radiological Protection Board as this becomes available’. The Approved Document refers to the present report for detailed guidance on where such protection is necessary and for construction details.
Although this report offers guidance in support of the Building Regulations for England and Wales, the technical solutions described are equally applicable for use in Northern Ireland, the Channel Islands and other countries where construction methods are similar to those in the UK. Guidance for Scotland, based on this report, is in preparation. No guidance is currently supplied for suspended timber ground floors in new dwellings. The DETR is sponsoring research into how this form of construction could provide adequate protection against radon and will publish the results in due course.
This guidance was not prepared for non-domestic buildings. However, protection from radon at work is specified in the Ionising Radiations Regulations 1985[3], legislation made under the Health and Safety at Work Act[4] administered by the Health and Safety Executive (HSE). The technical guidance contained in the present report may be of use to designers and builders of new structures whose form of construction and compartmentation is similar to housing and where the heating and ventilation regime is similar to that used in housing. This is likely to include small office buildings and primary schools. Further information is contained in the HSE/BRE guide Radon in the workplace.
